Abstract: The fresh leaves of Camellia sienesis (L.) Kuntze were distilled under low temperature and reduced pressure, the distillate thereof was extracted with ether, which gave rise to the volatile oil. From the volatile oil, by applying the GC, TLC, and IR, 51 components have been analyzed and identified. In addition, the variation law of the aroma of the fresh tea leaves in spring, summer and autumn has also been studied and determined. The main aroma of the fresh leaves of Camellia sienesis (L.) Kuntze are: cis-3- hexen-l-ol (spring, 2.15%; summer, 3.13%; autumn, 15%), benzyl alcohol (spring, 1.23%; summer, 1.60%; autumn, 1.01%), trans-linalooloxide (furanoid) (spring, 4.23%; summer, 4.11%; autumn, 3.18%), linalool (spring, 19.84%; summer, 8.20%; autumn, 11.91%), trans-linalooloxide (pyranoid) (spring, 1.73%; summer, 1.28%; autumn, 0.91%), geraniol (spring, 25.46%; summer, 3.93%; autumn, 3.16%), trans-2-hexenal (spring, 3.52%; summer, 25.48%; autumn, 1.13%), β-ionone (spring, 0.31%; autumn, 0.02%), cis-jasmone (spring, 0.20%; summer, 0.17%; autumn, 0.05%).
